Abstract

With the increasing penetrations of power-electronic-interfaced renewable power generation in the power system

the inertia of the power system continues to decrease. As a result

the frequency support and oscillation suppression capabilities of the power system continue to decline. To solve this problem

we propose a bilateral inertia and damping emulation（BIDE） control scheme for voltage source converter based high voltage DC transmission systems（VSC-HVDC）

enabling the inertial and damping responses to the both sides of VSC-HVDC interconnected AC grids.Firstly

the modeling and control of the VSC-HVSC and its communication system delay are briefly introduced. Then

a BIDE control scheme for a VSC-HVDC system is theoretically derived. In addition

a small signal model of the VSC-HVDC system is constructed and the stability analysis of the system is carried out. Finally

a back-to-back VSC-HVDC interconnected two-bus AC system model is established on the MATLAB/Simulink environment

and the proposed BIDE scheme is analyzed and verified under the events of load changes and three-phase fault. The results show that

under the proposed BIDE scheme

the VSC-HVDC system can simultaneously provide the bilateral inertial and damping power to the asynchronous AC systems interconnected at both ends

which can effectively improve the system frequency stability and enhance the oscillation suppression capability.
